Performance engineered: Enhanced frame structure and revised curve blade design to boost overall airflow (91.3CFM) and pressure (4.28 mm HO) Squama particle Patent: Squama particle on the frame, reducing turbulent flow noise increase airflow and pressure efficiency. PWM: 4-pin PWM controlled fan speed from 800 rpm to 2000 rpm, with excellent balance of performance and quietness, pushing up to 91.3 CFM of air with 4.28mm- HO of static pressure. Shockproof: Anti-vibration rubber pads can prevent scratches and further reduce noise from fan spinning at a higher level. ARGB Lighting: The 5V 3pin addressable RGB LED can synchronize lighting with motherboard, lighting effects are individually customizable. We also provide additional controller if your motherboard doesnt not support, that allow you could create your own immersive lighting effects without technical obstacle (7 lighting modes, 8 static colors).
